Canadian low-cost airline WestJet will formally sign a previously announced order for 65 Boeing 737 Max aircraft later today.
The scheduled contract signing comes less than a month after WestJet chief executive Gregg Saretsky signed the purchase agreement.
The deal, which is valued at $6.28 billion at Boeing’s list prices, includes 40 737 Max 8s and 25 737 Max 7s.
The first 737 Max will be delivered in September 2017, making Westjet one of the first operators to take delivery of the re-engined narrowbody.
All 737 Max aircraft will be powered by the CFM International Leap-1B high-bypass turbofan engine.
Westjet also has 42 current-generation 737s on backlog, including 28 737-700s and 14 737-800s.
The contract signing will increase Boeing’s overall sales total for the 737 Max to 1,563 aircraft. Westjet also becomes the 21st announced customer of the 737 Max model, which was launched two years ago.
In addition to new engines, the 737 Max features new split-tip winglets, a re-lofted tail cone and an extended nose gear.
